I have one EA which needs to be edited. Things to add is: when it makes Sell trade, you should add opening Buy trade, and if it makes Buy trade, you should add Sell trade. That is, opens hedge. But the size of original trade and your additional trade size can be different, and should be adjustable in the properties. Do not indicate the adjustable lot size for BUY and SELL! It should be adjustable for Original and Additional. Please, feel free if any question!
Thanks!
